Technical Specifications

Product Overview

The GE LU400/DX is a 400-watt Deluxe Lucalox® HPS lamp with improved color rendering. It ships with a ED28 bulb envelope on a E39 Mogul Screw base and is built to operate on an HPS ballast rated ANSI S51. Output is 37,400 initial lumens (34,400 mean lumens) at 2200K and 70 CRI, with a warm amber HPS color.

Deluxe Lucalox® HPS lamps combine the efficacy, lumen maintenance, and long life of standard Lucalox® with improved color rendering (65–70 CRI, much better than standard HPS). They blend well with incandescent and standard HPS sources and operate on standard HPS ballasts and auxiliary equipment.

Compatible Applications

• Typical uses (per GE): Storage rooms, industrial facilities, offices, gymnasiums, malls, parks, and building floodlighting.
• Fixtures wired for an HPS ballast rated ANSI S51 with a E39 Mogul Screw socket.
• Direct replacement for existing 400W HPS lamps with the same base and ballast rating. Verify ballast compatibility before ordering.
• Burning position: U (Universal — any burning position).

Before Ordering — Verify

• ANSI / Ballast Code: Confirm the existing lamp or ballast label matches S51.
• Wattage: Confirm the fixture is rated for 400W.
• Base Type: Confirm the socket matches E39 Mogul Screw.
• Ballast Compatibility: This lamp requires an HPS-rated ballast and ignitor. It will not operate on a metal halide or mercury vapor ballast.
• Burn Position: HPS lamps are not position-sensitive — no orientation restriction.
• Physical Fit: Confirm lamp shape (ED28), length (9.00" MOL), and clearance against the existing lamp or fixture manual.
• GE footnote: not for use with lampholders that have stainless steel center contacts, to avoid lamp or lampholder damage from arcing.
• Confirm order code 19650 (GE LU400/DX) exactly matches the lamp or ballast label on your existing fixture before purchasing a replacement.
• Case pack quantity is 12; confirm this meets your order needs.

Safety and Handling Guidelines

• Correct Ballast Required: Use only with an HPS-compatible ballast and ignitor rated for this lamp. An incompatible ballast can cause lamp failure or fixture damage.
• Vacuum Jacket: This is a vacuum jacket lamp and may implode if broken. Wear safety glasses and gloves when installing or removing the lamp, and allow it to cool fully first.
• Sodium Content: The lamp contains sodium — avoid skin contact with broken pieces (chemical burn risk).
• Warm-Up / Restrike: Per GE, HPS lamps take about 3–4 minutes to reach 90% light output after starting, and about 1 minute after a brief power interruption.
• Approved Fixtures Only: Install only in fixtures rated for the listed lamp type, wattage, and operating position; do not use if the outer glass is scratched or broken.
• Mercury Content: Contains mercury. Do not dispose of in regular trash; recycle through an approved lamp recycling program in accordance with federal, state, and local regulations.

Compliance

• Contains mercury — subject to applicable lamp recycling and disposal regulations. California, Washington, and other states may have mandatory take-back or handling fee requirements.
• Verify additional certifications (UL, Title 20, Prop 65) with the GE specification sheet prior to use in regulated installations.
